СУПЕРГІДРОФОБНІ ПОКРИТТЯ НА ОСНОВІ ВУГЛЕЦЕВИХ НАНОТРУБОК

This study focuses on the development of superhydrophobic coatings based on carbon nanotubes (CNTs), which exhibit unique structural and physicochemical properties. The research includes film materials with both aligned and non-aligned CNT structures prepared by various deposition techniques, such as chemical vapor deposition (CVD), spray coating, dip coating, and electrospinning. The primary objective is to analyze current strategies for fabricating CNT-based superhydrophobic surfaces, identify key parameters influencing the water-repellent performance, and evaluate the scalability and environmental compatibility of these approaches. The main finding highlights the effectiveness of both aligned and randomly distributed CNT films in achieving the Cassie-Baxter wetting regime, with contact angles exceeding 150° and low sliding angles. The study demonstrates that functionalization with hydrophobic groups, combination of CNTs with other nanomaterials, and optimized deposition parameters can significantly enhance surface hydrophobicity while extending the functionality of the coatings. These improvements include mechanical durability, self-cleaning ability, anti-icing behavior, and antifouling performance. The results underscore the potential of CNT-based superhydrophobic coatings for practical applications in fields such as energy, construction, transportation, and biomedical engineering.
